impacts of increasing gas curtailments and rising gas and electricity prices on farm profits, and on adjustments in crop patterns, water and energy use made in response to greater energy scarcity, were estimated for farms in pinal country, arizona. linear programming was used to estimate the profit maximizing acreage of alfalfa, upland cotton, pima cotton, barley, wheat and milo, and the profit maximizing level of water and energy use as natural gas is curtailed by up to 30 and the price of natural gas and electricity increase by 10, 25, 50, 100 and 200 percent respectively. the results showed that increases in the price of natural gas cut farm profits substantially. average farm profits on a medium sized farm (932 acres) pumping water from 555 feet were $26,000 in 1976. if the 1976 price of natural gas, $. 11222 per therm, is increased by 50, 100 and 200 percent, profits decline by $18,000, $34,000 and $68,000 respectively. if natural gas curtailments are 30 percent of normal use, farm profits are decreased by $8,000. implications for both on-farm and national and regional policy are given. 28 refs
